Downlights are a type of lamp introduced at the beginning of the reform and opening up in the last century.
They are called downlights in English. At first, the reflector cup inside could be seen. Later, for safety reasons, a cover was made on the outside,
which looked like a tube, so we took the It’s called a downlight.
The principle of downlights is the same as that of general lamps,
which is to convert electrical energy into light energy.
However, due to the advancement of the times, the advancement of light source technology, and the reduction of LED light source costs,
most downlights now use LEDs as Light source, environmentally friendly and energy-saving.
After the LED downlight is powered on, the electric energy is converted into the current and voltage required by the LED through the LED driver,
and then through a series of photoelectric conversion effects,
the electric energy is converted into light energy,
and the phosphor coated on the lens is excited to convert colored light. For white light.
Therefore, the usual structure of an LED downlight includes a ring cover,
a diffusion plate, a lamp body, a circlip, a power fixing bracket, a PCB or aluminum substrate, an LED, and an LED driving power supply.
Will downlights break easily?
J&S Lighting is a powerful LED lighting company in China.
Nowadays, most of the light sources used in downlights are LEDs. The theoretical life of a good LED light source can reach 50,000 hours. Generally, there is no problem if it is used for about 20,000 to 30,000 hours.
J&S Lighting was founded in 2010 and has been in business for 14 years. The optical technology of downlights has advantages, strict quality control, and LED is a mature technology.
So there is no need to worry about the quality of its downlights. However, care should be taken to protect the lines to avoid large currents. LEDs are driven by low currents.
Although an LED drive power supply is installed,
the stability of the circuit voltage and current is ensured, which is beneficial to extending the service life.
The LED light color of J&S Lighting downlights is uniform, and the color rendering index is close to 100. The color rendering index of ordinary downlights is only 80.
It uses a built-in drive power supply and has passed 3C certification. It is a high-quality downlight.
What are the maintenance methods for downlights?
The best maintenance method for downlights is basically done when purchasing and installing them.
When purchasing, choose downlights with reliable quality, good workmanship, and good optical quality:
for example, good heat dissipation performance, comfortable light appearance, good spot effect, etc.
When installing, pay attention to connecting the neutral and live wires to avoid the slight brightness after turning off the lights.
After installation, it can be used normally.
The installation method and structural characteristics of the downlight itself determine that there is nothing special to pay attention to or maintenance methods after normal use.
In addition, most of today’s downlights have an integrated design. Lamp manufacturers generally do not recommend replacing the driving power supply or light source separately. If it is broken, go directly to the after-sales service or replace it.
